Question 1:<span> 5x + 10 = 5x –8
5x - 5x + 10 = -8
10 </span>≠ -8
Hence, the answer is A.
Question 2:<span>2(4y –1) = 6
8y - 2 = 6
8y = 6 + 2
8y = 8
y = </span>
<span>
y = 1
Hence, the answer is B.
Question 3:</span><span>6x + 10 –4x = –4 –11
2x = -15 -10
2x = -25
x = </span>
x = -12.5
Hence, the answer is B.
Question 4:<span>2(2x –5 –4) = 160 –17
4x -10 -8 = 143
4x -18 = 143
4x = 143 + 18
4x = 161
x = </span>
x = 40.25
Hence, the answer is A.
Question 5:<span>2(3x –7) + 18 = 10
6x - 14 + 18 = 10
6x + 4 = 10
6x = 10 -4
6x = 6
x = </span>
x = 1
Hence, the answer is A.
Answer: 12 square units
Step-by-step explanation: first you must count hom many units there are between points A and B, which is 4, and then count the points between B and C, which is 6.
Now that we have the units we do 6 x 4 = 24, however, you may be asking why we do not do 24 then, well if you were to be doing 6 x 4, you would be getting the area of a rectangle, and half of a rectangle is a triangle, so we have to do 24/2 which equals 12.
To figure out velocity<span>, you divide the distance by the time it takes to travel that same distance, then you add your direction to it.</span>
